Link establishing method, communication terminal and computer readable storage medium

Abstract

The invention discloses a link establishment method, a communication terminal and a computer readable storage medium. The method comprises the steps of: enabling a calling party to send a first numberof call requests on a first number of first frequency points in a preset frequency band; receiving a response message, wherein the response message comprises at least part of a second number of response messages sent by the called party on a second number of second frequency points in a preset frequency band after the called party receives the call request, and an optimal first frequency point selected from the first number of first frequency points; selecting an optimal second frequency point from the second number of second frequency points, and generating a confirmation message containingthe optimal second frequency point; and determining an optimal first frequency point from the response message, and sending an acknowledgement message to the called party to establish a call link. Thecalled party receives the call request in the wide receiving mode, and / or the calling party receives the response message in the wide receiving mode. By means of the mode, the link establishment probability and the communication quality of short-wave communication can be effectively improved, and the link establishment duration is shortened.

Description

technical field [0001] The present application relates to the communication field, and in particular to a link establishment method, a communication terminal and a computer-readable storage medium. Background technique [0002] In various communication networks, it is usually necessary to establish a call link between communication terminals to realize communication between the two parties. The communication signal quality in the communication network is the main factor affecting the link establishment of the call. For example, for a short-wave communication network, its radio waves must be reflected by the ionosphere to reach the receiving device, and the communication distance is relatively long. Since the height and density of the ionosphere are easily affected by factors such as day and night, seasons, and climate, the stability of short-wave communication Poor and noisy. At present, because the channel ionosphere of short-wave communication transmission is fluctuating...

Problems solved by technology

For example, for a short-wave communication network, its radio waves must be reflected by the ionosphere to reach the receiving device, and the communication distance is relatively long. Since the height and density of the ionosphere are easily affected by factors such as day and night, seasons, and climate, the stability of short-wave communication poor, noisy

At present, because the channel ionosphere of short-wave communication transmission is variable, the communication frequency is changing in different weathers, regions, and at different times. The probability of link establishment in short-wave communication is low, and the communication quality is also easily affected.
